To all whom it my concern.'

Be it known that I, GATAN BRUN, a citizen of the Republic of France, andresiding at Paris, Seine De artment, No. 1 Rue Jules Lefebvre, in theepublic of France, have invented certain new and useful Improvements inSelf-Propelling Cranes, (Case B,) of which the following is aspecification.

This invention has for its object to provide an improvedself-.propelling traveling crane soconstructed that the motor thatpropgls the vehicle sha-1l likewise be capable of ing utilized foroperating the crane, that is to say, to slue the crane around on its ownaxis and tc wind up the lifting rope.

An improved apparatus according to this invention is illustrated by wayof example in the accompanying drawings in which:

Figures 1 and 1a are a side elevation partly in section of the entireapparatus 2 is a horizontal section of the lirting Fig. 3 isa horizontalsection showing the lower l driving mechanism.

Fig. 4 is a. vertical section of the sluing mechanism, and Fig. 5 is anelevation partly in section of the turn-post.

'As shown,*the frame A of `the improved traveling crane is similar tothe frame of a motor lorry but of larger dimensions, since its-partsmust-be designed to withstand the strains to 'which 'they will besubjected.

In front of the frame is an engine 1 with a cooling radiator fitted witha fan. The drivin shaft is connected te a change speed box 3 hrough themedium of a clutch 4 and a shal'tZ.`

This cha e speed box comprises preferably toothe wheels adapted to givetwo cds to the vehicle. From its lower part l t ere issues a shaft 5driving a rear dierof the change Speed box, and operated by means of apedal 11, while the other brake 12 is adapted to act upon the hindwheels and is operated by means of a hand lever 13.

In front of the vehicle two seats S S1 are provided set face to face,and capable of serving simultaneously, one for the driver whencontrolling the travel of the vehicle, and the other for the driver, oranother person when operating the crane.

The lifting mechanism consists of an ordinary jib crane provided with acabin L inclosing the machinery. A fixed portion P situated on the frameA of the vehicle carries the control mechanism F, while a movableportion H B carries the lifting winch K.

A turn-post 14 mounted on a ball .and socket bearing box 14 fixed to theframe of the vehicle, carries by means of a yoke 15 the revolvingplatform H, B of the crane.

A shallow dish-shaped plate 16 mounted on the turn-post supports thedriving mechanligsem of the Izre l arings 1 i 1 and 3 ca shafts 18 and19. The liaft 18 is )conlnlefzted by means of the shaft 9 and Cardancouplings to the speed-reducing device 8", and it drives through apinion 20 a toothed wheel 21 that is loose on the shaft 19. This toothedwheel can be operatively connected tothe shaft 19 by means of a clutch22 preferably of the friction type which "is adapted to slide on afeather-key on said shaft. This shaft carries also an automatic liftingbrake cornprising a pulley 23, a plate 24 and a spring 25.

On the turn-post 14 (Fig. 5) there is mounted on balls a hollow shaft 26carrying a bevel pinion at each end. The lower pinion receives motionfrom the pinion 27 that is fixed on the shaft 19, and transmits thismotion through the upper pinion to the lifting winch. A

For driving the sluin mechanism, there is provided on the end o `theshaft 18 (Fig.

a double clutch, preferably of the friction type, comprising a sleeveV28 sliding along a feather-key on the shaft 18. This sleeve allows ofthrowin into gear one of the two conical inions 9 and 30 that are looseon the shag 18, and of driving in one or the other direction a beveltoothed wheel 31 that is fixed on a worm shaft 32.

A pinion 33 (Fig. 4) loose on its shaft 34, can be operatively connectedto the latter by means of a claw clutch 35 slidable along a feather-keyon said shaft and operated by f fixed a pinion 37 for driving a ring ofteeth ymotion (Fig. 3).

a sliding shaft 36, the handle 36 of which slides over a cam 36". Y

By means of this arrangement the revolving portion is free to revolvearoundV the turn-post 14 so as to allow of operating two apparatuses inseries for handling articles of great length. f v 1 On the upper end ofthe shaft 34 there 1s 38 fixed on the revolving crane platform H (Fig.la).

On the end of the worm shaft 32 there is fixed a pulley 39 for brakingthe sluing shaft 42 and actuated by one of the conical pinions fixed tothe tube 26, drives through a pinion 46 a toothed wheel 47 that is fixedon the lifting drum 48 carriedby a shaft 43.

The shaft 44 carries an auxiliary drum 49 on which is wound a rope'forraising the j ib M. This drum is-driven by a toothed wheel 50 meshingwith the wheel 47. This wheel 50 is loose on the shaft 44 and can be0peratively connected theretoby means of a clutch 5l, 1;)referablykofthe friction type,

Y slidable along a featherfkey on the said Y 40 i shaft.

A hand brake 52 fitted to the drum 49 serves for regulating the loweringof the jlb. c

For the sake of security a ratchet wheel 53 is fixed on the drum 49.

The raisingrope passes over guide pulleys 5 5 to the pulleys 54 at thehead of the jib and to the lifting hook R.

The jib is held by tie-rods 56 and can lbe raised and lowered by theropes passing from the drum 49 over pulleys 57.

It istobe understood that the apparatus is so designed as to enable allthe movements to take place slmultaneously'7 that is to say,

itis possible at one and thevsame time to lift theload, to sluethe load,and to transportl theload, while moreover the crane can rotateindefinitely around its turn-post. On the other hand, the crane drivenwho is seated on a seat whichr does not rotate with thecrane, remainsstationary on the vehicle during the operations.
